To all whom it may concern:

Be it known that I, NEWMAN H. HOL- LAND, a subject of the King of Great Britain, and a resident of \Vest Orange, in the county of Essex and State of New Jersey, have made a certain new and useful Invention in Phonographs, of which the following is a description.

My invention relates to phonographs and more particularly to an improved record support therefor.

Ordinary phonograph records change in diameter to a considerable extent under different temperature conditions, expanding under heat and contracting under cold, whereas the supports upon which the records are mounted change but little in diameter under the same conditions. As

these supports are so constructed that when 20- the' records are placed thereon, a tight engagement will be maintained between the same and the records, it frequently happens that the latter become so tightly locked in place that it is difficult to remove them without damaging the record surface or breaking the records themselves.

The object of my invention is to provide a record support adapted to firmly hold a sound record or a. sound record blank and yet to permit its ready removal. In

'conformity with this object, I preferably provide a support in which the record engaging means is movable toward and from the axis of the support so that the said means may be firmly held in engagement with the bore of the record or blank or moved inwardly to permit disengagement of the latter.

e Other objects of my invention Will appear more fully in the following specification and appended claims.

In order that my invention may be more fully' understood, attention is hereby directed to the accompanying drawing forming a part of this specification and in which- Figure 1 representsa vertical longitudinal sectionthrough the center of the mandrel of a phonograph embodying my invention, a part of the frame of the phonograph being shown in elevation; Figs. 2, 3, 4 and 5 represent sections of the mandrel taken on lines 22, 3+3, 4-4, and 5-5, respectively, of Fig. 1; and Fig. 6 represents a fragmentary section of a modification of one of the details of construction.

In all of the views, corresponding parts are designated by the same reference numerals.

The phonograph to. which my invention is shown applied in Fig. 1 is of well known construction and comprises a bed plate 1 provided with standards 2 and 3. Support- 1 Fig. 1, engages the corresponding end of the tube at and cooperates with the enlargement 9, engaging the end of the bearing 7, to prevent the shaft 6 from shifting longitudinally with reference to the tube 4. Power is transmitted to the driving shaft of the phonograph by means of a belt (not shown) encircling the pulley 10 rotatable on the shaft 11 which latter is secured in the standard .2 by ascrew or equivalent means 12.. A screw 13 or other equivalent means engages in the groove 14 in the shaft 11 to preventm'ovement of the pulley 10 axially of the said shaft. The shaft 11 is axially in line with the shaft 6, to which it is adapted to beconneoted by a clutch 15, which is slidable back and forth upon the enlarged portion 9 of the driving shaft 6. Gear 16 is secured to the portion 9 of the shaft 6; and from this gear by connections (not shown) the feed screw of the phonograph is driven in the usual manner.

I My improved record support comprises a tubular shaft 17 secured at one end as by friction. to the collar 8, so as to rotate With Y the shaft 6, and provided at its other end end thereof and secured thereto by a screw 21 or other desired fastening means. A

second rigid flange or disk 22 is slidably mounted on the shaft 17 adjacent the outer end thereof. The flange or disk 19 is provided with a number of equally spaced .openings 23 at equal distances from the axis the record support. Fitting loosely in eachopening in the flange or disk 19 and a corresponding opening in the flange 22 is a rod or member 25 adapted to engage the bore of a phonograph record cylinder A. These rods, as shown, are preferably cylindrical in form; and, as more clearly shown in Figs. 3 and 4, the openings therefor in the flanges 19 and 22 extend throughout slightly more than a semi-circle so that the said rods 25 are retained against disengagement laterally from the said flanges and at the same time extend slightly beyond the latter, so that each presents an unobstructed portion adapted to engage the bore of the record. The openings or seats 23 and 2+ are made slightly larger in diameter than the rods, so as to permit an easv movement of the latter therein during the manipulation of the device. By reason of the location of the openings 21 nearer the axis of the support than the openings 23. the support formed by the rods 25 has a slight taper toward the outer end thereof. It is evident that when the distance between the flanges or disks 19 and 22 is decreased by moving the flange 22 inwardly, the taper of the said support will increase sufliciently to permit the removal of the record therefrom. the flange or disk 19 acting as a fulcrum for the rods 25. In order to permit an easy manipulation of the flange or disk 22, I provide the same with a cup-shaped portion 26 slidably mounted on the shaft 17, this cup-shaped portion being preferably provided with a knurled head 2! to facilitate the operation thereof. A coiled spring 28 or other suitable compression member is located between the end of the bore of the cup-shaped member 26 and the collar 8 and serves to hold the flange or disk 22 inits outer position, thereby retaining the members 25 in firm engagement with the bore of the record. The pin 29 or other suitable guide is secured to the shaft 17 and cooperates with a longitudinal slot 30 in the cup-shaped member 26 to hold the flange 22 with its openings in axial alinement with the openings in the flange 19. This pin also serves by its engagement with the ends of the said slot to limit the axial movement of the cup 26 and flange 22.

In order to prevent longitudinal movement of the rods or record engaging members 25, I preferably employ the flange or disk 31 provided with a collar 32 secured to the shaft 17 as by set screw 33, this set screw also preferably serving to hold the bearing 18 in position within said shaft. This flange is provided with radial slots or openings 31 adapted to receive the reduced necks 35 on the rods these necks forming shoulders adapted to engage the opposite faces of the flange 31 to prevent longitudinal movement of the said rods. As shown in the drawing, the flange 22 is slidable longitudinally over the rods 25.

In Fig. (3 I have shown a record engaging rod 25 tapering inwardly, as shown at 36, over the portion adapted to be engaged by the flange 22, whereby the amount of inward or outward movement of the rods 25 for a given amount of longitudinal shifting of the flange 22 is materially increased.

In using my invention, the record may be placed upon the support by merely sliding the same along the rods 25 until it is firmly held thereon by friction. When it is desired to remove the record, it is simply necessary to force the member 27 inwardly to collapse the record support, whereupon the record may be easily removed by hand, even though previous to the collapsing of "the support it may have been securely shrunk or clamped thereon.

\Vhile I have shown certain preferred embodiments of my invention, I do not wish to be limited to those disclosed, as my invention may evidently be carried out in numerous other ways. In short, my invention is limited only as defined by the terms of the appended claims.
